The alpine rating is Wind Slabs., the treeline rating is , and the below treeline rating is Known problems include
Wind slabs remain active. Be prepared to alter your plans if you see signs of instability.
On Thursday in the Bullmoose area; small windslabs of varying ages (some fresh and some old and hard) were reported. See photos here.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
In the alpine, up to 15 cm of recent snow is heavily wind affected and sits above a variety of old snow surfaces including wind-scoured snow and faceted snow. At treeline and below, the recent snow sits on a widespread crust and pockets of surface hoar.
The snowpack is shallow and faceted with multiple crusts. Pockets of deeper snow may be found near ridges, gully features, and established avalanche paths. Average snowpack depths at treeline are between 50 and 90 cm.
Cloudy with 5-10cm of snow, southwest alpine wind 30-50 km/h, treeline temperature -15 °C.
Cloudy with up to 3 cm of snow, southwest alpine wind 30-40 km/h, treeline temperature -14 °C.
Cloudy with a trace of snow, south alpine wind 20 km/h, treeline temperature -18 °C.
Cloudy with up to 5 cm of snow, southwest alpine wind 40 km/h, treeline temperature -8 °C.

Terrain and Travel Advice
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Avalanche danger is often elevated in alpine gullies where snow has accumulated.
Northeast wind likely created complicated patterns of wind effect, and formed wind slabs on south and east-facing slopes.
Aspects: South East, South, South West, West.
